Concrete resonant cone speaker system

ABSTRACT

A speaker system for use in conjunction with a high fidelity system, the speaker system being placed within a room, and including a vertically upstanding truncated cone of hollow character and which tapers upwardly toward a top opening, the lower end of the concrete cone being mounted upon a wood base that supports a speaker, the wood base including a top ring, intermediate ring and flat bottom piece surrounding the speaker, the top ring, intermediate ring and bottom piece being spaced apart by means of the support separators.

CONCRETE RESONANT CONE SPEAKER SYSTEM This invention relates generallyto sound speaking systems.

A principal object of the present invention is to provide a concreteresonant cone speaker system which gives a false dpeth to a room withoutan expensive reverberation unit and delay system.

Another object of the present invention is to provide a concreteresonant cone speaker system wherein the delay is accomplished by thetime factor required for a sound wave to travel up the concrete cone andbounce off of the ceiling and reach a listener.

Yet a further object of the present invention is to pro- .vide aconcrete resonant cone speaker system wherein a choking effect of thesound wave occurs as the sound wave travels up the concrete. cone,because of the slightly conical shape thereof, much the same as a chokeof a shotgun, which helps to prevent the sound wave from spreadingbefore it reaches the ceiling.

Yet a further object of the present invention is to provide a concreteresonant cone speaker system wherein the unit has a 360 sound spreadfrom the base (nondelayed sound) and the sound projecting off of theceiling.

Other objects of the present invention are to provide a concreteresonant cone speaker system which is simple in design, inexpensive tomanufacture, rugged in construction, easy to use and efficient inoperation.

These and other obejects will be readily evident upon a study of thefollowing specification and the accomapnying drawing wherein:

FIG. 1 is a side elevation view of the tion shown partly incross-section, and

FIG. 2 is a cross sectional view taken on the line 2-2 of FIG. 1.

Referring now to the drawing in detail, the reference numeral representsa concrete resonant cone speaker system according to the presentinvention wherein there is a concrete cone 11 made of concrete drainagetile and which comprises a conical side wall around a central opening 12extending through the truncated cone. The concrete truncated coneis'placed upon a wood base 13 and extends vertically upwardly with thetapered end of the truncated cone being at the top.

The wood base 13 supports a speaker 14 located on the vertical axis ofthe concrete truncated cone so that sound from the speaker is directedinto the interior 12 of cone 11. The wood base 13 is comprised of acircular flat bottom piece 15, intermediate ring 16, top ring 17 and aplurality of support separators. A plurality of four support separatorsl8are placed between the bottom piece 15 and the intermediate ring 16while another set present invenof four supportseparators 19 are placedbetween the intermediate ring 16 and the top ring 17, it being notedparticularly in FIG. 2 that the support separators l8 and 19 are out ofalignment with each other. A circular support separator 20 of ring shapeis fitted within the lower end of central opening 12, the supportseparator 20 being secured upon the top ring 17 concentricallytherewith. The speaker 14 is secured to the underside of the top ring17.

In operative use the hollow tile may contain a tuned resonant column ofair. The base is especially designed to isolate the concrete drainagetile from the floor so that it will not be damped by contact with thefloor. The support separators l8 and 19 are strategically placed betweenthe rings and the bottom piece in disaligned position as indicated. Thisisolates the concrete tile much the same way as the tines on a tuningfork are isolated.

There is a 360 low level, linear delay off of the side of the drainagetile, as the sound wave travels up the tile. The lip on the top ringsupports separator 20 is fitted into the lower end of the concretetruncated cone. Wood screws are used to secure the speaker to the bottomof the top ring. Wood screws are used to secure the top ring to thesupport separators and they are also counter sunk to keep them frominterfering with the lip of the concrete drainage tile when it is set ontop of the base.

What I now claim is:'

1. ln a concrete resonant cone speaker system, the combination of a woodbase for placement upon the floor of a room, and a vertically upstandingconcrete truncated cone placed upon said wood base, said wood basecontaining a speaker in alignment with a lower end of said concretetruncated cone for moving sound waves upwardly through said concretetruncated cone so as to give a false depth to a room without anespensive reverberation unit and delay system, wherein said concretetruncated cone comprises a one piece member made of concrete drainagetile, said concrete truncated cone consisting of a conical side wallaround a central opening extending there through, said concretetruncatedcone supported upon said wood base being tapered upwardlytoward a smaller end at its top, and wherein said wood base consists ofa circular bottom piece, an intermediate ring in spaced relation abovesaid bottom piece and a top ring in spaced relation above saidintermediate ring, said rings and bottom piece having a plurality ofsupport separators there between, and said speaker being secured to anunder side of said top ring.
